I think I have the same problem sometimes as the OP. If I start a flight and finish it I need to reboot FSX I use a couple of addons which make use of FSUIPC and think that because of this there is a lot of memory being used. Nevertheless Im surprised by this (Im not a pc guru). So after all flights I reboot all programs. My PC specs are not low IMHO:
Win 7 64 bit
32 GB Ram
Processor: i& 4930K 3.4 GHZ
Video card: GeForce GTX 750 Ti
I use to TV screens connected by HDMI to this card.
I have a SSD of 100 GB and run windows on this disc I have a dedicated HD for flight simming which is not SSD but has 749GB space at the moment only 491 is being used.
I would espect not to have any problem but still sometimes i have issues. So im eager to follow this thread and if anybody could give me some nice recommendations feel free to give them to me
Thanks in advance,
